This is the amount in your utility bill that you will save by generating your own electricity. This value assumes that you export 50% of the electricity generated and that you use the remaining 50% yourself. The calculation assumes an average electricity price of 12p per kWh, but remember that this will inevitable increase in the future, meaning your savings will be even greater!
The total energy saved figure is a combination of the feed-in tariff, export tariff and electricity saving components of the PV system's financial benefits.
